Market restrictions on the lifting and transportation equipment production

Over the past few decades, the trends of globalization and the markets expansion have been fundamental in the Russian and world economies. Such economic structure requires a large volume and range of transportation, the storage systems presence, the transported objects distribution. Logistics centers become an integral part of the economic development both for the regions and the country as a whole. Logistics centers, in turn, need specialized equipment that allows the most efficient use of existing storage areas. Reach truck is one of the most commonly used equipment in large A and A + warehouses. The article presents the estimating market restrictions method when the equipment cost determining taking into account the characteristics of the designed facility and the main competitors represented on the market. The method peculiarity is taking into account the technical and consumer characteristics of the investigated object, their comparison with the competitors' parameters. Based on this comparison, the possible product price is determined. The proposed technique allows to optimize equipment configuration and price depending on the consumers' needs. The proposed evaluation algorithm was tested on complex technical equipment (reach truck), but it should be noted that the proposed methodology is universal and can be applied to any technical object. © Published under licence by IOP Publishing Ltd

Fine-mesh photodetectors for CMS Endcap Electromagnetic Calorimeter

The behaviour of fine-mesh vacuum phototriodes (VPTs) with the external diameters of 21 and 35 mm has been investigated in an axial magnetic field up to 4 T in view of their applications as readout devices for CMS Endcap Electromagnetic Calorimeter. The measured VPT parameters are: the photocathode's sensitivity and its homogeneity, the gain in zero and 4 T magnetic field at tilt angles corresponding to the pseudorapidity range of CMS ECAL Endcap 1.48-3.0 as a function of fine-mesh cell dimensions, excess noise factor and the stability of the photocathode response under the illumination by light emission diodes (LED) and the irradiation by 14 MeV neutrons. Phototriodes with 100 lines per mm fine-mesh and 25 mm external diameter are found to be the best candidates for coupling with rear PbWO/sub 4/ crystals by dimensions of 30*30 mm, proposed to be used in CMS ECAL Endcaps. VPTs provide a gain of the order (6-8) in a 4 T magnetic field and an excess noise factor of 2-2.5 under illumination of a full photocathode's area. (2 refs)

Fine--Mesh Photodetectors for CMS Endcap Electromagnetic Calorimeter

The behaviour of fine-mesh vacuum phototetrodes and phototriodes ( VPTs) in an axial magnetic field of ( 0 -- 4)T has been investigated. The measured VPT parameters are: fine-mesh cell dimensions, the photocathode sensitivity and its homogenity, the gain in zero and 4T magnetic field at tilt angles corresponding to the rapidity range of CMS ECAL Endcap 1.479 -- 3.0 and excess noise factor. Measurements have been performed on 21 and 30 mm diameter photodetectors with different fine-mesh structures: 30, 60 and 100 lines per mm under different types of photocathode illumination by green LED. Phototriodes with 30 or 60 lines per mm and an external diameter of 21 mm are found to be the best candidates for the CMS environment with the initial size of PWO crystals proposed to be used in the Endcap, by comparison with phototetrodes. They provide a gain of the order of 6 -- 8 in 4T magnetic field and an excess noise factor of 2 under full photocathode illumination

The CMS experiment at the CERN LHC

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1) (10(27)cm(-2)s(-1)). At the core of the CMS detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. The iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4 pi solid angle. Forward sampling calorimeters extend the pseudo-rapidity coverage to high values (vertical bar eta vertical bar <= 5) assuring very good hermeticity. The overall dimensions of the CMS detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500 t

CMS physics technical design report: Addendum on high density QCD with heavy ions

This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies ,will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction - Quantum Chromodynamics (QCD) - in extreme conditions of temperature, density and parton momentum fraction (low-x). This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include "bulk" observables, (charged hadron multiplicity, low pT inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high pT hadrons which yield "tomographic" information of the hottest and densest phases of the reaction.0info:eu-repo/semantics/publishe
